Key Parameters
Power: 27kW
Temperature: 842°F (450°C)
Time: 5 sec
Process:
- The two copper tubes were placed together in the coil.
- Induction heating was applied for 5s.
- Improved process control for uniform induction heating to a desired temperature
- Power on demand and rapid, consistent heat cycles
- Technology without pollution, which is both clean and safe
